Figure 1-1. Percentage of U.S. Adults Ages 18 Years or Older Who Met the
Aerobic and Muscle-Strengthening Guidelines, 2008–2016
Source: Centers for Disease Control and Prevention, National Center for Health Statistics, National Health Interview Survey (NHIS).
Notes: Estimates are age-adjusted to the 2000 U.S. standard population using five age groups: 18–24 years, 25–34 years, 35–44 years,
45–64 years, and 65+ years. NHIS questions ask about frequency and duration of light-intensity to moderate-intensity and vigorousintensity
leisure-time physical activities, as well as the frequency of muscle-strengthening activities. Meeting the aerobic component
of the 2008 Physical Activity Guidelines for Americans is defined as reporting at least 150 minutes of moderate-intensity or 75 minutes
of vigorous-intensity aerobic physical activity a week, or an equivalent combination. Meeting the muscle-strengthening component is
defined as reporting muscle-strengthening activities at least 2 days per week. Error bars represent upper and lower bounds of the 95%
confidence interval.
